o2 sensor alarm
I have a 2004 cavalier. The check engine light comes on for a day or two and
then goes off for a day or two. The scan tool says it is a bad o2 sensor. When
I put the tool in live data mode the sensor has a reading of .1 to .9, which I
was told is a normal reading. Any thougths on what the problem may be?
What is the 4 digit code? something else can be triggering the O2 code to detect a lean or rich condition.
I did not see 4 digit code. Will hook the scan tool back up and see what the code is.
what do u do if it says lean condition mine is p0171
I hooked the scan tool back up and the code said P0130. However the check engine light had already gone off. Keeping the tool in the car so it the light comes back on I can check it again.
